A Closer Look at RIPE100’s Qualifying Practices: Covers on Waste Lagoons

RIPE’s researchers continually work to expand the set of practices that would qualify for $100 per unit payment under the proposed RIPE100 program by collecting research that demonstrates the combined environmental value of climate-smart practices.

The use of covers on waste lagoons (NRCS code 367) for swine and dairy animal feeding operations is one qualifying practice. Lagoon covers can reduce emissions and provide additional environmental benefits valued at over $840 per animal unit per year.

We found that farmers who implement lagoon covers reduce greenhouse gas emissions by around 2.2 metric tons per animal for a public value of $43 per acre. They also provide at least $780 per animal unit in air quality benefits. 

Cover types included in this methodology: Lid (wood or concrete), tent covering, plastic film, plastic fabrics, expanded clay, expanded polystyrene, plastic tiles, peat, straw cover, and vegetable oil.
